i have a 1998 npr . the i e coolant light started coming on when first cranked truck then goes off. but yesterday i noticed it came on and stayed on and buzzer stayed on too. i checked the coolant but it seems to be fine and temp gets up to normal also. what would cause this to happen? also my oil filter is leaking very badly where it connects. i know i will need to replace the filter but is this the reason why my coolant light comes on and buzzer sounds.
